so much affected. They flower from April to August. (Son 

 No. 9.) 



Aloysa citriodora, known in our collections as verbena 

 triphylla. The flowers are small, in long spikes of a pale 

 lilac colour; the celebrity of the plant is in the delightful 

 odour of its foliage, which is linear, lanceolate, and ternate. 

 It is of very easy culture, and has been known to survive 

 winter in the open air in Philadelphia. Where large plants 

 are desired, they should be planted in the ground during 

 summer, and lifted in November, and put in a dry cellar or 

 under the stage in the green-house. Before they begin to 

 grow in the spring, trim the plants into a neat shape. (Soil 

 No. 9.) 



Alstroemerias, about sixteen species, all exceedingly de- 

 sirable, and many of them particularly beautiful ; such are 

 A. durea, golden-flowered; A. b icolor, salmon and orange; 

 A. carminata, carmine-coloured ; A. Hookerii, rose-coloured ; 

 A. pelegrina, elegantly spotted; A. pulchella, red-flowered, 

 and will grow six feet high, having its shoots crowned with 

 a profusion of flowers ; A. psittacina, red, yellow and green ; 

 A. tricolor, black, white and yellow; very beautiful. They 

 have, generally, tuberous roots, and should be potted into 

 fresh soil as soon as they show symptoms of growth, and they 

 will require repotting about every month previous to flowering, 

 taking care never to break the ball of earth while they are in 

 a growing state. (Soil No. 10.) 



Amaryllis This is a genus of splendid flowering bulbs, 

 containing about eighty species and one hundred and forty 

 varieties. They are natives of South America, but more than 

 one-half of them are hybrids grown from seed by cultivators. 

 They are generally kept in the hot-house, but in our climate 

 will do perfectly well in the green-house ; and we have no 

 doubt that in a few years many of them will be so acclimated 

 as to keep as garden bulbs, planting about the end of April, 

 and lifting them in October. As the beauty of these plants 

 is in the flowers, it will be proper to give a small description 

 of a few of them. A. bella, pure white striped with rose; 

 A. Bartonii, creamy white striped with pink; A. Buistii, 

 large pure white, striped with cherry colour; A. ignescens, 

 bright red, with white at the base of the petals. A. Johnsbni, 

 the flowers are a deep scarlet, with a white streak in the centre 

 of each petal, four bloom on a stem of aVout two feet, each
